Problems solved by technology

The existing preparation methods of one-dimensional metal compound nanocrystals are mainly vapor phase method and electrochemical deposition method. These preparation methods generally require special equipment and complicated operations. Some require higher temperatures, which is not conducive to actual operation. It needs to consume a large amount of expensive inert gas, which greatly increases the preparation cost of preparing one-dimensional metal phthalocyanine compound nanocrystals, so it is not conducive to large-scale production
